Beginning in 1997, Central Europe between the Baltic and Adriatic Seas was covered by an unprecedented network of seismic refraction experiments (POLONAISE'97, CELEBRATION 2000, ALP 2002, and SUDETES 2003) that were only possible due to a massive international consortium consisting of more than 30 institutions from 16 countries in Europe and North America. The biggest experiment (CELEBRATION 2000) included 147 shots recorded by 1230 seismic stations forming, during three deployments, an array of ∼8900. km of profiles. The total length of seismic profiles in all these experiments is ∼20. 000. km. During these four experiments, 295 large explosions provided the seismic sources. The majority of recording instruments were provided by the IRIS/PASSCAL Instrument Center and the University of Texas at El Paso (USA). The main results of these experiments are delineation of the deep structure of the southwestern margin of the East European craton (southern Baltica) and its relationship to younger terranes; delineation of the major terranes and crustal blocks in the Trans-European Suture Zone (TESZ); determination of the nature and extent of thrust faulting along the northern front of the Carpathians; improved understanding of the origin and structural framework of the Pannonian basin; improved knowledge of deep structure of the Eastern Alps; determination of the structural relationships between the structural elements of the Bohemian massif and adjacent features; development of three-dimensional models of the crustal structure; and development of new geodynamic models for the tectonic evolution of the Central Europe.
